Otherwise du is as fast as you can ever get - think about it - if perl

Performance isn't the only consideration. Perl is a pretty heavy-duty
pre-req for a simple command like du.

As a matter of fact, du itself is sometimes too much of a resource hog.
Research the busybox command which is used to reduce the overall footprint
by implementing simple versions of many of these system utility commands
in a single, small, executable.

Remember, unix-like software often runs in small embedded devices with
little memory and/or disk space.

BUT -- it is unlikely that there could be any substantial improvement on
the performance of the du command. Depending on how critical this and
other filesystem performance is, the original poster could investigete
which harware, filesystem, and/or operating system best meets his needs.
